## Description
This PR introduces the `cmdtest` package, offering a lightweight wrapper around cobra commands to simplify testing CLI utilities.
I backfilled tests for the `version` command, which was an example of a very simple test setup; and for the `export` command, which was more involved due to the server and client context requirements.
I did notice that there are some existing tests for some utilities, but the `cmdtest` package follows a simple pattern that has been easy to use successfully in [the relayer](https://github.com/cosmos/relayer/blob/main/internal/relayertest/system.go) and in other projects outside the Cosmos ecosystem.
While filling in these tests, I started removing uses of `cmd.Print`, as that is the root cause of issues like #8498, #7964, #15167, and possibly others. Internal to cobra, the print family of methods write to `cmd.OutOrStderr()` -- meaning that if the authors call `cmd.SetOutput()` before executing the command, the output will be written to stdout as expected; otherwise it will go to stderr. I don't understand why that would be the default behavior, but it is probably too late to change from cobra's side.
Instead of `cmd.Print`, we prefer to `fmt.Fprint(cmd.OutOrStdout())` or `fmt.Fprint(cmd.ErrOrStderr())` as appropriate, giving an unambiguous destination for output. And the new tests collect those outputs in plain `bytes.Buffer` values so that we can assert their content appropriately.
In the longer term, I would like to deprecate and eventually remove the `testutil` package's `ApplyMockIO` method and its `BufferWriter` and `BufferReader` types, as they are unnecessary indirection when a simpler solution exists. But that can wait until `cmdtest` has propagated through the codebase more.

The version package is meant to be a convenience utility
that provides SDK consumers with a ready-to-use version
command that produces app's versioning information from
flags passed at compile time.
It will not make sense anymore for the baseapp package
to depend on the version package once gaia will have been
migrated away from the SDK main repository as we neither
want to make assumptions nor set expectations on downstream
apps buildsystems. Thus BaseApp now provides SetAppVersion()
and AppVersion() to to allow SDK consumers to set BaseApp's
version information string once the struct is initialised.
* version prints out short info by default
Handle -o json, add --long flag to print full version info.
* Add distclean target to Makefile
* Update PENDING.md
* Add missing targets in .PHONY
